Section 180-4-023 - CONTROL OF ACCESS TO HIGH RADIATION AREAS The requirements for control of access to high radiation areas are as follows.
023.01ACCESS POINTS. The licensee or registrant must ensure that each entrance or access point to a high radiation area has one or more of the following features:(A) A control device that, upon entry into the area, causes the level of radiation to be reduced below that level at which an individual might receive a deep dose equivalent of 1 mSv ( 0.1 rem) in one hour at 30 centimeters from the source of radiation from any surface that the radiation penetrates;(B) A control device that energizes a conspicuous visible or audible alarm signal so that the individual entering the high radiation area and the supervisor of the activity are made aware of the entry; or(C) Entryways that are locked, except during periods when access to the areas is required, with positive control over each individual entry.023.02CONTINUOUS DIRECT OR ELECTRONIC SURVEILLANCE. In place of the controls required by 180 NAC 4-023.01 for a high radiation area, the licensee or registrant may substitute continuous direct or electronic surveillance that is capable of preventing unauthorized entry.023.03APPLICATION FOR APPROVAL OF ALTERNATIVE METHODS. The licensee or registrant may apply to the Department for approval of alternative methods for controlling access to high radiation areas.023.04EGRESS. The licensee or registrant must establish the controls required by 180 NAC 4-023.01 and 4-023.03 in a way that does not prevent individuals from leaving a high radiation area.023.05RADIOACTIVE MATERIALS PACKAGED AND LABELED FOR TRANSPORT. The licensee is not required to control each entrance or access point to a room or other area that is a high radiation area solely because of the presence of radioactive materials prepared for transport and packaged and labeled in accordance with the regulations of the U.S. Department of Transportation provided that: (A) The packages do not remain in the area longer than 3 days; and(B) The dose rate at 1 meter from the external surface of any package does not exceed 0.1 mSv ( 0.01 rem) per hour.023.06PATIENTS CONTAINING RADIOACTIVE MATERIAL. The licensee is not required to control entrance or access to rooms or other areas in hospitals solely because of the presence of patients containing radioactive material, provided that there are personnel in attendance who are taking the necessary precautions to prevent the exposure of individuals to radiation or radioactive material in excess of the established limits in 180 NAC 4 and to operate within the as low as reasonably achievable (ALARA) provisions of the licensee's radiation protection program.023.07EXCEPTION. The registrant is not required to control entrance or access to rooms or other areas containing sources of radiation capable of producing a high radiation area as described in 180 NAC 4-023 if the registrant has met all the specific requirements for access and control specified applicable chapters of Title 180, 180 NAC 5 for industrial radiography, 180 NAC 6 for x-rays in the healing arts, or 180 NAC 9 for particle accelerators.180 Neb.
